Measurement of cross sections of threshold detectors with spectrum average technique

Abstract

Summary Cross sections of the reactions 103Rh(n, n′)103mRh, 115In(n, n′)115mIn, 232Th(n, f), 47Ti(n, p)47Sc, 64Zn(n, p)64Cu, 58Ni(n, p)58Co, 54Fe(n, p)54Mn, 46Ti(n, p)46Sc, 27Al(n, p)27Mg, 56Fe(n, p)56Mn, 24Mg(n, p)24Na, 59Co(n, α)56Mn, 27Al(n, α)24Na and 48Ti(n, p)48Sc were measured with average neutron energies above effective threshold by using the activation method through usage of spectrum average technique in an irradiation system where there are three equivalent Am/Be sources, each of which has 592 GBq activity. The cross sections were determined with reference to the fast neutron fission cross section of 238U. The measured values and published values are generally in agreement.
